Interactive Dendrograms

Interactive dendrogram that enables the user to select and color clusters, to zoom and pan the dendrogram, and to visualize the clustered data not only in a built-in heat map, but also in 'GGobi' interactive plots and user-supplied plots. This is a backport of Qt-based 'idendro' (< https://github.com/tsieger/idendro>) to base R graphics and Tcl/Tk GUI.
